When you open the Amazon page, across the top they list their specials (or at least they do on my iPad app), and one of those is Last Minute Deals. When you open this, it has deals of the day, and Lightning Deals, both of which have a limited amount , and are timed sales. Underneath each item, it says what percent are gone, and how much longer the sale lasts. Some items are slow to sell, and some go really fast. My friend, @Ina I. Wonder , had said that she needed a flash drive, and they had $80 ones for $12; so I started to message her and let her know; but before I even finished the message, they were all sold, and the sales ad disappeared ! So, today, when I saw more at a similar saving , I let her know right away, and she just got hers before they were sold out. Much of the items advertised are (to me) just useless stuff like jewelry and things that are just foo-foo, and have no practical purpose. Of course, if you like that kind of thing, then I guess it is not "useless stuff", and there is LOTS of it ! ! Being a practical type of person,and a Gadget Girl; I like things that have a useful purpose in life. I found a $71 self-warming dog bed for just $12, so now Chipper has a new bed coming in the mail to keep him warmer this winter. There were watches that retail for around $700, and priced for under $50; so you can find some amazing bargains if you browse through the deals each day.
